The movable platform accommodates main equipment:
- centrifugal fan;
- chanel electrical heater;
- system of valves and air ducts of various shapes and materials;
- microprocessor- based measuring system.
Air ducts are designed as circular 100 mm diameter and rectangular cross-section pipes made of PVC, circular transported 100 mm diameter pipe, flexible 100 mm diameter hose made of PVC. The ducts are mounted on the front side of the mounting frame.
The measuring system allows to register static and dynamic pressure in metering sections, rotation speed of the fan impellers, voltage, current, active power of the fan electric motor, air temperature in the duct. Differential pressure transducers are used to measure static and dynamic pressure. Pressure sensors are connected to air ducts via a system of tubes.
Microprocessor-based control and measuring system has a modular design combining autonomous units. Microprocessor-based system includes the following units:
- inlet unit;
- power supply unit;
- pressure measuring and tachogenerator unit;
- power measuring unit;
- pressure and temperature measuring unit.
The laboratory stand is accompanied by a set of guides and technical documentation for the teaching personnel.
